Abstract

A portable terminal includes a main housing, a sliding housing coupled to the main housing in such a manner that it can slide to expose or hide a part of a surface of the main housing, a keypad module positioned on the main housing and adapted to be exposed or hidden as the sliding housing moves, and a driving means positioned on the main housing to cause the keypad module, when exposed by the movement of the sliding housing, to protrude from a surface of the main housing. The sliding movement of the sliding housing is converted into up-and-down movement of the keypad module to overcome the difference in level among the upper surface of the sliding housing, the display device, and the keypad for convenient key input.
